Example Showing a basic idea of dividing the second flood gallery into the perimeter zone, interior zone, and core zone.
5 different building schemes
1. Resultant amounts of lighting power,lighting equipment, & lighting energy
2. Resulting air conditioning load that comes from light fixtures assuming all are on
3. Balance point temperature(BPT) for building schemes
4. Corresponding Watts/ sq.ft
5. Heat gain through the skin
6. Internal Loads the same for all 25 schemes
Daylight Design Performance
Lighting Power Density: The ratio of lighting power to square footage measured in w/sq.ftR-values of materials
Corrugated Steel Roof 1'6"- .0032(18) = .058
Double Air Filled Glass - .14(2) + 5.6 = 5.88
Concrete 2' Wall - .7(24) = 16.8
Total sq.ft of Building = 25,650
